Sadly, longer jail time is purely placebo. Plenty of studies show jail time has no incidence on crime rate. Sure, locking people for longer would delay recidivism, but we could do better than that.
It’s not about logic though. Longer jail time proponents do lean on the emotional argument of a few anecdotal cases or recidivism. This tend to make flashy headlines and stick with the population.
This is fascinating! I couldn’t find much info on that and actually, what I found implies that there were some on Canadian bases not just in Canada, but around the world. That is, from if old letters from the Diefenbaker Center are representative of history.
